[Respiratory syncytial virus pneumonia in four immunocompromised adults].

Introduction: In hematologic malignancies, respiratory syncytial viral infections can be explained by neutropenia, and cellular and humoral immunodepression, and may cause severe respiratory infections.

Exegesis: Four patients with hematologic malignancies developed a severe respiratory syncytial virus infection. Three of them had previously received autologous bone marrow transplantation (ABMT). Progress was favorable for three patients. One patient died of acute respiratory failure.

Conclusion: When such patients present with respiratory symptoms, especially during the winter months, they should be screened for RSV. Bronchoalveolar lavage allowed quick and accurate diagnosis by immunofluorescence. Treatment with nebulized ribavirin is controversial. Its use may be interesting in patients with high-risk factors (intensive chemotherapy, ABMT, diffuse pneumonia with hypoxemia).
